Robin: “Holy molars! Am I ever glad I take good care of my teeth!”
Batman: “True. You owe your life to dental hygiene.”

Education:

Dick: “Awww, heck! What’s the use of learning French anyway?”
Bruce: “Dick, I’m surprised at you! Language is the key to world peace. If we all spoke each other’s tongues, perhaps the scourge of war would be ended forever.”

Batman: “The green button will turn the car a la escarda o a la drecia.”
Robin: “To the left or right. Threw in a little Spanish on me, huh, Batman?”
Batman: “One should always keep abreast of foreign tongues, Robin.”

Dick: “Wow! The rings of Saturn! This is sure some fun, Bruce.”
Bruce: “Astronomy is more than mere fun, Dick.”
Dick: “It is?”
Bruce: “Yes, it helps give us a sense of proportion. Reminds us how little we are, really. People tend to forget that sometimes.”

Dick : “What’s so important about Chopin?”
Bruce : “All music is important, Dick. It’s the universal language. One of our best hopes for the eventual realization of the brotherhood of man.”

Dick: “Sorry, I’m not interested in dance lessons.”
Bruce: “Wait a minute, Dick. The junior prom’s coming up, isn’t it?”
Dick: “Yes, but…”
Bruce: “Well, we don’t want you to be a wallflower, do we? Dancing is an integral part of every young man’s education.”

Robin: “I guess you can never trust a woman.”
Batman: “You’ve made a hasty generalization, Robin. It’s a bad habit to get into.”

Batman to Robin: “When you get a little older, you’ll see how easy it is to become lured by the female of the species.”

Politics:

Batman: “Better put 5 cents in the meter.”
Robin: “No policeman’s going to give the Batmobile a ticket.”
Batman: “This money goes to building better roads. We all must do our part.”

Dick: “Gosh, Economics is sure a dull subject.”
Bruce: “Oh, you must be jesting, Dick. Economics dull? The glamour, the romance of commerce… Hmm. It’s the very lifeblood of our country’s society

Robin: “Gosh, there could be diplomatic repercussions if we fail this time, Batman.”
Batman: “That’s not the point, Robin. What’s important is that the world know that all visitors to these teeming shores are safe, be they peasant or king.”
Robin: “Gee, Batman, I never thought of that. You’re right.”
Batman: “It’s the very essence of our democracy.”

Batman: “Nobody wants war.”
Robin: “Gee, Batman. Belgravia’s such a small country. We’d beat them in a few hours.”
Batman: “Yes, and then we’d have to support them for years.”
Who knew Batman was so full of wisdom?
